为什么栈溢出的代码加了sleep就好了？

写了一个静态累，单例模式，里面有一个线程定时读取配置，调用下面的GetAppSetting方法，这样服务安装完，要更改配置不需要重启服务，但是诡异的是多线程的调用下会报堆栈溢出，然后程序就崩了
更诡异的是在方法中加了Thread.Sleep(10);程序正常了
private static string GetAppSettings(string key)
{
Thread.Sleep(10);
if (ConfigManager.Current.appSettings.ContainsKey(key))
{
return ConfigManager.Current.appSettings[key];
}
return string.Empty;
}
下面是所有的代码
